Check your page on the Sims 3 website and see if those games are showing as registered there. My problem (and probably most of the others on this thread) is that the games are being registered, but they are not correctly showing up in the "My Games" section of the website.
They only show up in the game launcher and in origin.
I have had this happen twice. Last weekend I bought 3 expansion packs, and I was in online chat with an EA game advisor for more than an hour. In the end they had to get new codes for the games and register them.
Since their is a big sale going on now, I bought more expansion and stuff packs yesterday. Same issue. Game advisor had to register the games for me using new codes.
This thread has hundereds of people with the same problem, and I don't recall see any official answer from EA. I hope they get this fixed before The Sims 4 comes out next summer. I don't want to have to go through this every time I buy a new game.
